"Very well, come in, perhaps you can do a demonstration and then someone can book an assembly room for you. Do you have poor vision? Do we need to light the place?"

"My vision is fine and if need be I can enhance it further by magic." She floats in.

It's very very large, and descends downwards in a way that suggests it's even much larger than that, and it's all very intricate well-done stonework.

Odette carefully memorizes as much of the stonework as possible to show Illia later.

Her guides explain things she looks particularly interested in. An assembly room, she is told, has been booked so she can give a talk.

Great. It's definitely a good thing she's had so much practice explaining magic lately so this isn't totally impromptu.

The talk isn't for a few hours, though, so they can show her around or leave her to prepare.

This place is beautiful and she would love to be shown around.

People are mostly quite cheerful and they pass her, and she's greeted in heavily accented Sindarin. There are Dwarven children running around.

Aww, children not inextricably linked to major drama.

They have beards, too!

...Species diversity! You learn something new every day.

And then the elaborate stone amphitheater fills for her talk.

Right then.

She starts out by explaining that magic as she knows it has three branches, and the difference in methods between the three, and the side effects, pain and mental both, and the differences in side-effect between the branches, and how resistance and meditation work, and what she's been able to accomplish with her magic so far while she was here, and a great many things magic was used for back in her original world.

There is a lot of enthusiasm.

Good.

At some point it comes up that learning magic has thus far required osanwe.

Dwarves are immune to mind-affecting magic. Because mind-affecting magic is terrible.

...Yes, yes it is. That...does complicate things, though.

Presumably humans back home don't have osanwë?

They do not! Unfortunately she has no memory of not being able to do magic, never thought to ask how it happens, and can't communicate with her original universe right now. If anyone has any ideas she would love to test them.

Some people have ideas. They also have ideas for things she could effectively trade them for (magic weapons, most obviously, in exchange for gems and metals she can replicate easily).

She can do that. She's not as good at prettying gems as her sister but making them isn't hard. She's also very interested in testing any viable-seeming magic transferral ideas.

How is magic taught back home? How was it first invented?

Magic is taught back home with the assumption that you're already familiar with the core sensations that are what osanwe is necessary for. The invention--or discovery--of magic happened independently in every culture on her planet and long before when historical records go back to.

Hmmm. So maybe with enough background familiarity Dwarves will pick it up too? It must be derivable. They determinedly try.
